Abstract

Abstract Processes of synthesis, isolation, and purification of benzylpenicillin β- diethylaminoethyl ester hydroiodide were studied. The optimal conditions of benzylpenicillin esterification with chloroethyldiethylamine in dimetylformamide and acetonitrile were found. Processes for isolation of the target product were developed and its physicochemical properties were studied. Product stabilization conditions providing a stable pH value in ...
